since Lauren and Singer wanted DOFP since a long time ago, at one point they had to realize that they needed a different cast for the scenes in the past (or an older cast for the scenes in the future, in case they wanted original actors as present timeline)

But... since Fox wanted a young x-men spinoff...... what if Bryan and Lauren agreed to do FC as the preparation for DOFP, and that X4 treatment is the very next step after this sequel?

what if this was the plan since day one? at least by Lauren and Singer

Well that sounds really smart and creative. They just didn't create the First Class movie to show things that happened in the past but to also eventually connect it to the original cast.

I still dont get why people insist on calling a non X3 follow up X4. That time is done.

Its not yet done until its over. There are a lot of movie franchises out there that it took them a long time to do the fourth movie.
